It studies taxi passenger's daily travel behavior feature: first, it analyzes temporal distribution of them and proposes the solution of dynamic management of taxis by limiting operation period; second, through investigating the uneven spatial distribution of taxi travel demand and nonlinear correlation of travel density and population density, it reveals the shortcoming of linear matching transportion facility with population number in traditional urban transport criterion, also it questions the limited effect of the licence management for taxis, and it proposes dynamically determing taxi scale according to different traffic zones; third, through exploring the taxi travel patterns in special zones, it reveal Hong Kong citizens travel behavior in Shenzhen, which could analyze the impact of demographic feature to the travel behavior and provide scientific testimony for designing transportion service for the special group; fourth, through accurately grasping the spatial-temporal distribution of taxi travel demand, it could provide innotiative and efficient transportion service at different time and in different place, such as taxi-sharing and flexible shuttle to meet the travel demand; through pervasive data, we could inspect urban expansion and sprawl, monitor the separation of inhatitantion center and employment center and reflect the variation of population centriod and distribution; finally, it reveals how to use digital feature of inhabitant daily travel to detect abnormal condition in the city.

对出租车乘客的日常交通行为特征进行了研究：通过对出租车出行时间分布特征的把握，提出采取限时营运的方法来对出租车进行动态管理的思路；通过分析出租车出行空间分布不均匀的特征以及出行密度与人口密度之间非线性的关系，揭示了传统城市交通规范中按人数来线性配套交通基础设施的缺陷以及牌照管理对于出租车管理的有限效果，提出按照区域动态确定营运出租车规模的思路；通过特定区域出租车出行特征的分析，揭示香港居民在深圳的交通行为特征，从而分析不同人口统计特征对于交通行为的影响，为设计这个特殊群体的交通服务提供科学依据；通过对出租车出行时空分布特征精确的把握，使得我们可以在不同时间、不同地点采用创新、高效的交通服务，如合乘出租车，高级穿梭巴士来满足出行需求；通过普适数据可以监测城市的扩张和蔓延、居住中心和就业中心的分离程度以及反映人口重心与分布的变化；最后探讨了如何利用居民日常出行的数字特征来检测城市异常状态。
